Adjusting Level Accuracy
•
When the accuracy of the Piper has been checked, and the amount of error is
known, the beam position is adjusted using the UP and DOWN arrow buttons (c)
to increment the counter and move the beam to the desired position.
•
Each count represents approximately two arc seconds. Therefore, five counts of
the counter is approximately equal to 1.6 mm at 30 meters (1/16 inch at 100
feet).
•
The Piper icon will blink to indicate that the unit has not reached the level posi-
tion.
•
The LEFT or RIGHT arrow buttons (d) may be used to move the line during this
procedure.
